This is what I have had done on mine. Dual 2.5" with SS resonators on each side. Using the stock tips.
It does sound good. With a nice note on the outside, without being to loud.
But there is a bit of drone on the inside, under 3000 rpm. Which can become quite tiresome after awhile. No drone while cruising though.
I have sort of fixed it up by blocking one side with some steel wool. Now there is no drone at all inside. But still sounds the same on the outside.
I think it's because the pipe has stayed 2.5". There is not enough exhaust gas volume going through both the resonators.
And with that slow down in exhaust gas. Is creating the drone. So I'm going to be removing one of the resonators & replacing it with a straight pipe with a electronic valve.
Then when I want it quite, the exhaust gas will go through the resonator. When I want a bit more noise, it can go through the straight pipe..
I think completely removing both resonators & just having straight dual pipes, also induces the drone..
Video of when I got the exhaust done.. You can also hear the intake as well..
